IMPROVEMENT IN ATTACHMENTS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 126,467, dated May 7,1872; antedated April 24, 1872.

To all whom it may concern:

Be it known that we, G. G. LAWRENCE, of Fitchburg, in the county ofWorcester and State of Massachusetts, and A. A. WOOD, of Fitchburg, inthe county of Worcester and State of Massachusetts, have invented a newand useful Improvement in Sewing-Machine Attachment; and we do herebydeclare that thefollowing is a full and exact description of the same,reference being had to the accompanying drawing and to the letters ofreference marked thereon.

This invention has for its object the production of a simple andefficient device for ruffling, basting, &c.; and consists of certaindetails of construction, which will be fully described hereinafter.

In the drawing, Figure 1 represents a plan view of our improved devicein position for rufliling. Fig. 2 represents an elevation of same. Fig.3 represents a plan view of the parts of the device swung apart fromeach other Fig. 4, a plan view of the device in position to be used forfringing.

To enable others skilled in the art to make and use our invention, wewill now proceed to describe fully its construction and operation.

A represents a metallic strip, of suitable shape, provided, at one end,with an orifice, a, by means of which it is attached to the machine, andat the "other with a finger, a and projection to, as shown. It isfurther provided, upon its lower side, with a pin, a, and upon its upperside, also, with a pin, a, which latter is threaded and provided with asetscrew, a as shown. B also represents a strip of metal, whichresembles, in its general shape, the strip A. It is also provided, atone end, with an opening, b but at the other it has the projection b andopen slot 11.

The operation is as follows: The plate B is laid upon the plate A, asshown. in the drawing, and both are attached to the machine, by means ofthe orifices a b, by the same screw that holds the other attachments.When it is desired to use the device for rufliing, the piece of goodsthat is to be ruflied passes over the finger a and under the remainingend portion of plate A, out beneath the projection a The piece to whichit is to be attached passes between the projection b and the end ofplate A. From this arrangement of the parts, it will be observed thatthe upper piece-that is, the goods to which the ruflie is to be attachedmay be held back in its movement by causing the plate B to press more orless heavily upon it through the medium of the set-screw a", while thelower piece, or the goods to be ruffled, is freely moved by the feed. Ittherefore follows that the lower piece of goods necessarily moves fasterthan the upper, and that, consequently, it is formed into gathers orrutfles, in which position it is fastened to the upper piece by theaction of the needle. By adjust'in g the pressure upon the plate B, thepiece of goods which forms the foundation of the ruffle will be more orless retarded, and, consequently, the ruffling will be made more or lessfull.

If it is desired to use the device for seaming or basting, the operationis as follows: If the edges of the cloth to be united are even with eachother, they should be run beneath the finger a and out of the recess a,formed between it and the remaining end of the plate A, the end of therecess serving as a gauge to guide the edges of the cloth. If it isdesired to have one edge of the cloth further from the seam than theother, one may be run through the recess 00, and the other throughbetween the plates B and A.

The device may also be used for fringing, if desired, by arranging theplates A B as shown in Fig. 4, in which case the space 00 will serve asa gauge for the depth of the fringe.

From this peculiar construction this device is adapted not only forrufiing, but also, as before described, for sewing a seam withoutbasting, the edges of the cloth being even with each other for ordinaryseaming, or otherwise for the purpose of felling, as may be desired. Itis also adapted for serving as a gauge for fringing. It is adapted topermit the accomplishment of these results mainly because the plates areseparated from each other, by which means the upper plate is enabled toswing upon its pivot and form a variable gauge. In connection, also,with the power to vary the relative position of the plates, the peculiara in combination with the plate B, provided with the finger b and recess6 the plate B being adapted to swing upon its pivot, as described, forthe purpose set forth.

This specification signed and witnessed this construction of the endswith the slots and 3d day of July, 1871.

projections is important.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-
